Lentigines

Lentigines, or liver spots, are benign lesions that occur on the sun-exposed areas of the body. They are also commonly called liver spots. The backs of hands and face are common areas. These irregularly-shaped darkly-colored spots can be as large as two centimeters.

Causes

These lesions are caused by a marked increase in the number of pigment cells located in the superficial layers of the skin.

Symptoms

The lesions tend to increase in number with age, making them common among the middle age and older population. They can vary in size from 0.2 to 2 cm. These flat lesions usually have discrete borders, are dark in color, and have an irregular shape.

Diagnosis

A doctor will perform a physical examination to diagnose lentigines, and a biopsy will be necessary if it is irregular to ensure it is not cancerous.
